SPECIFICATION forming part of Letters Patent No. 356,094, dated January18, 1887.

Application filed November 9,'1886. Serial No. 218,390. (No model.)

To all whom, it may concern:

Be it known that we, DENNIS S. BLUE and LEANDER HALTER, citizens of theUnited States, residing at Fremont, in the county of Sandusky and Stateof Ohio, have invented certain new and useful Improvements inOultivators; and we do hereby that the following is a full, clear, andexact description of the same, reference being had to theannexeddrawings, making a part of this specification, and to the lettersand figures of reference marked thereon;

Figure 1 of the drawings is a perspective view of our improvedcultivator; Fig. 2, a top plan View partly in section; Fig. 3, a detailsectional view taken on line as x of Fig. 2; Fig. 4, a similar viewtaken on line y y, and Fig. 5 a detail sectional view through the seatand seat-support.

The present invention has for its object t0 provide apractically-constructed and easilyoperating cultivator; and it consistsin the details of construction substantially as shown on lthe drawingsand hereinafter described and claimed.

In the accompanying drawings, the frame Aris composed of tubing a,coupled together at their forward ends by elbows I), the sides of thelrame having connected thereto, by coupling-sections c, a transversebrace-rod, (Lto which is connected the tongue of the cultivator, asshown at B. This tongue in the present instance is formed of the twosections ef,- but, if preferred, a single section may be used.

The crank-axles C at their upper ends are connected to thecoupling-sections c and eX- tend down and outwardly, and upon their eX-tremities are mounted the wheels D. rIhe upper ends of the axles Carescrew-threaded, by means of which they. are securely connected to thecoupling-sections c, as shown in Fig. 3, as are also the ends of thetransverse brace d. The ends of the tubes @,which form the frame of thecultivator, are also screw-threaded to couple with the elbows b. Thelower. end of the crank-axles C have connected to them braces E, theends of which are widened, as shown at g, to form ashoulder or collarfor the hub of the wheel, the upper ends of said braces being connectedin any suitable manner to the forward end of the frame of the machine.

The cultivator-beams are of the ordinary shape, and at their front endsare connected together to form a slot, h, to receive the drawbar F.There are shown three beams, G, to each cultivator, their rear endsbeing curved in the usualmanner for attaching thereto the shovels H. Informing the slots h the outer ones of the beams G are-formed of onepiece of metal, and the middle beam disposed between them and fastenedin position so that a slot will be left, as above described.

The draw-bars F are curved at their upper ends and bifurcated, as shownat z', to receive grooved rollers k, which work on guides I, suitablyattached to transverse rods Z, connected to suitable 'clips projectingfrom the under side ofthe frame of the machine, or in any other suitablemanner attached thereto, as found preferable. The rods Z form the innerguide for the rollers k, thereby retaining the pulley in position whileworking laterally on the guides, when the cultivators move laterally ineither direction. The draw-bars F have perforaiions m at their lowerends to receive bolts n, whereby the cultivator-beams may be raised orlowered to regulate the depth of cultivator, as shown more clearly inFig. 4, a suitable nut, o, engaging with the screwthreaded end of thebolts. The cultivators may also be raised or lowered by means of thedouble-crank arm K, suitablyjournaled to the sides of thecultivator-frame, as shown at p, and to clips q on thev rear extremitiesof the tongue-sections ef.'

The double crank arms or levers K are connected to the cultivator bymeans of standards or links L, said levers being pivoted or looselyconnected to the upper ends thereof,

the standards being bifurcated to embrace the sides of two of thecultivator-beams. The

double-crank levers are bent to form handles,

ner ends of each section, a suitable distance ICO throughout its length,have perforationse, through which passes a suitable screw-bolt, w, uponthe end of which engages a tightening-nut, w', to secure thespring-sections together and also secure the seat thereto. By the abovemeans provision is'made for lengthening or shorteningI the springtoincrease or diminish its iexibility. The rods O, to which the spring isconnected, extend through the tubesa of the frame, and are held thereinby setscrews a', and areconsequent-l y adjustable, to change theposition ot' the seat as circumstances require. By lifting the curvedhandles r of the double-crank levers K the crank portion thereof,tonwhich the bifurcated standards L are connected, when brought forwardbeyond a vertical line will fall of its own weight until the standardsrest against the transverse brace d, which will securely hold thecultivators from ot'f the ground.

One or both of the cultivators may be provided with the usual handle, P,and the tubes 'and couplings forming the frame of the ma` chine renderthe frame not only strong and durable, but comparatively light.

As will be noticed, the coupling-elbows b of the frame A are providedwith depending lugs bf as a means for attaching thereto the extremitiesof the transverse rod Z, held thereto by means of nuts c', engaging thescrew-threaded ends of the rod. The coupling-sections c are alsoprovided with like lugs, for connecting thereto the rear one of the rodsZ. The eyes or clip p, which form the bearings for the double-cranklevers K, project from the rear end of the coupling-sections c, therebyforming a strong and permanent fixture for the levers.

When the cultivators are moved from right to suit different persons.

As previously described, two different means are employed for connectingthe sleeves s of the spring to the extremities of the rods O, viz: akey, t, and a latch, u, said latch acting as a hinge, so that when thekey is removed one end of the spring may be detached, or by disengagingthe latch with the rod 0 this end maybe removed, while the opposite endis held bymeans of the key, thereby enabling the driver to get in andout of his seat. The rods O are drawn out of the tubes a sufficiently sothat the driver can balance the tongue, this being an important featureof our invention, as well as other details of construction, hereinbeforedescribed. The bifurcated standards L are-.connected to the beams of thecultivator by means of a strong and substantial the beams, and alsoforming a brace therefor,

the two serving to steady the cultivator when in operation.

As will be noticed, two rods Z are shown, for convenience of using ariding Lor walking Cultivator, the forward one of said rods being usedfor attachment thereto of a ridingcultivator. One or both of saidcultivators ymay be provided with a stirrup, It, to receive the foot ofthe driver, to move the cultivator to either the right or the left. Thewalking-cultivator is made by asimple change,

the rod Z being placed in the rear of the riding-cultivator at theproper distance, so as to. take the draft andY weight of the tongue,

in order to balance without the weight of driver, as is more clearlyshown in Fig. 2, the same connections being made between the cultivatorbeam and rod; but the `draw-bar F is reversed, as shown in dotted lines,Fig. 4.

By this change the cultivator is kept in the same line with theriding-cultivator, and the manner of attaching the cultivators preventstheir hanging back of the wheels when turning. f

One draw-rod Z will answer for both riding and walking cultivator wheneither is used separately. The stirru p R is detachable, so that it maybe removed when the device is used as a walking-cultivator.

Having nowv fully described our invention, what we claim as new, anddesire to'secure by Letters Patent, is-

1 In a frame i'orcultivators, the metal tubes @coupling-elbows b, andcouplingsections c, roo having depending lugs, as shown, and the formerhaving eye-clips p, iu combination with the transverse brace (Z, rodsZ,.and the doublecrank levers la, links L, and beams G, substantially asand for the purpose specified.

2. The combination, with the extensible rods O, of the extensible oradjustable spring seatsupport N, provided at its extremities' withsleeves s, and detachably connected to the ends of therods,substantially as and for the purpose 1ro set forth.

3. ln a cultivator, the frame A, constructed as described, thetransverse guides l, and rods Z, in combination with the plow-beams, thecrank-levers K, for raising and lowering them, i 15 andthe curved andbifurcated draw-bars F, provided with grooved rollers k, substantiallyas and for the purpose set forth.

In testimony that we claim the above we have hereunto subscribed ournames in the .12o presence of two witnesses.
